Water resource management is a key issue for environmental sustainability in Australia and strategies that include ecological principles are important to improve present conditions and reduce further degradation. Current biomonitoring methods suffer from a low degree of sensitivity that can seriously impact their effectiveness as early warning signals of ecological disturbance. We propose to combine molecular and ecotoxicological assessment of the effect of zinc toxicity on microbial communities to provide rapid pollution sensitive bioassessment. Our research will lead to a better understanding of the cause and effect of heavy metal pollution within aquatic ecosystems and greater insight on how to reduce and repair the negative effects.Read moreRead less
Effects of ants and ant-mediated dispersal on speciation rates, biogeography and diversity of angiosperms. This work seeks to improve our general understanding of longstanding questions in ecology in evolution, namely what are the processes that have allowed some groups to become diverse and others not, why does dispersal mode vary with geography, and how do speciation and extinction vary across space, time and taxon? In answering these questions, we will address some of the most fundamental que ....Effects of ants and ant-mediated dispersal on speciation rates, biogeography and diversity of angiosperms. This work seeks to improve our general understanding of longstanding questions in ecology in evolution, namely what are the processes that have allowed some groups to become diverse and others not, why does dispersal mode vary with geography, and how do speciation and extinction vary across space, time and taxon? In answering these questions, we will address some of the most fundamental questions in conservation, including what are the factors that make species geographically rare, which species are most at risk for climate change, and what are the factors that have led habitats like the Kwongan Heath and Fynbos to be so exceptionally biodiverse.Read moreRead less
Comparative Biogeography of Australasian biota. Establishing an internationally recognised biogeographical research program will help scientists, policy makers and the public understand the past and future distribution patterns of the plants and animals of Australia. Discovering these patterns will help conservation biologists and government implement the right policies and practices to deal with biodiversity loss and climate change.

Insights into macroevolution using a model adaptive radiation of lizards (Lerista). Australia has arguably the greatest diversity of lizards in the world. This research will investigate how this diversity arose, using Lerista, a radiation of skinks with over 80 species spanning fully limbed to totally legless forms. We will investigate how development, geographic distribution and morphological features have influenced the evolutionary diversification of Lerista. We will also map the biodivers ....Insights into macroevolution using a model adaptive radiation of lizards (Lerista). Australia has arguably the greatest diversity of lizards in the world. This research will investigate how this diversity arose, using Lerista, a radiation of skinks with over 80 species spanning fully limbed to totally legless forms. We will investigate how development, geographic distribution and morphological features have influenced the evolutionary diversification of Lerista. We will also map the biodiversity of Lerista across Australia using (and thus testing) several alternative methods of quantifying biodiversity. Such knowledge is important as many hotspots of Lerista diversity are coming under increasing human pressure (e.g. mid-coast of WA), and many species have very localised ranges.Read moreRead less
Altering host-parasite interactions through wildlife conservation strategies. Disease outbreaks are heightened in endangered animals but strategies used to conserve these species often increase risk of disease; nowhere is this more critical than in species recovery programs. The project will study disease in a recovery program to improve conservation practice and protect Australia's wildlife, ensuring our ecosystems are sustained.
Managing genetic diversity and evolutionary processes in foundation species for landscape restoration in the midwest of Western Australia. This project analyses genetic structure in four key plant species used for post mining restoration across the midwest. It will provide guidelines for seed collections that ensure planted populations will persist at altered sites after mining and that planted and natural populations can adapt to changing future environmental conditions.

The biodiversity consequences of evolutionary innovation. This project aims to increase knowledge of how evolutionary innovations affect biodiversity. This project will focus on a classic example of evolutionary innovation, the specialized throat jaws found in many fish groups, including damselfishes, wrasses, and cichlids. These unique jaws may explain why these fish groups contain so many species and are such successful invasive species in Australia and elsewhere. This project proposes an inte ....The biodiversity consequences of evolutionary innovation. This project aims to increase knowledge of how evolutionary innovations affect biodiversity. This project will focus on a classic example of evolutionary innovation, the specialized throat jaws found in many fish groups, including damselfishes, wrasses, and cichlids. These unique jaws may explain why these fish groups contain so many species and are such successful invasive species in Australia and elsewhere. This project proposes an integrative combination of methods and functional experiments to reveal the biodiversity consequences of evolutionary innovation. It will also enhance Australian biosecurity through the production of new ways to assess invasion risk from aquaculture and aquarium trade species.Read moreRead less
Experimental evolution of trait interactions under changed environments. This project aims to use altered light in laboratory and wild guppy populations to test directly the following questions: which traits evolve quickly or slowly and how does this depend upon their functional interactions, and how often do different solutions to the same environmental challenges evolve? The evolutionary effects of environmental change on gene regulation and functional interactions among traits are virtually u ....Experimental evolution of trait interactions under changed environments. This project aims to use altered light in laboratory and wild guppy populations to test directly the following questions: which traits evolve quickly or slowly and how does this depend upon their functional interactions, and how often do different solutions to the same environmental challenges evolve? The evolutionary effects of environmental change on gene regulation and functional interactions among traits are virtually unknown. Using evolution experiments, this project aims to explore traits with known functional links: opsin gene regulation patterns (for colour vision), colouration, and colour-based choice. It is expected that vegetation changes cause immediate environment changes, directly affecting animals’ abilities to choose mates, forage, and avoid predation.Read moreRead less

Bayesian Hierarchical Model for Biogeography. Species Distribution Models (SDMs) are crucial tools for conservation and planning, but they assume that environmental variables (e.g. temperature) are the only controls on distributions, when historical factors, like dispersal limitation and phylogenetic niche conservatism, are also important. A Bayesian Hierarchical Model (BHM) will be constructed to jointly estimate dispersal history, niche evolution, and present-day SDMs for each species in a cla ....Bayesian Hierarchical Model for Biogeography. Species Distribution Models (SDMs) are crucial tools for conservation and planning, but they assume that environmental variables (e.g. temperature) are the only controls on distributions, when historical factors, like dispersal limitation and phylogenetic niche conservatism, are also important. A Bayesian Hierarchical Model (BHM) will be constructed to jointly estimate dispersal history, niche evolution, and present-day SDMs for each species in a clade. BHMs will be tested against traditional SDMs using Australian clades (e.g. frogs) and simulations. BHMs will advance scientific understanding of how species and biogeography coevolve and provide practical improvements in predictions for species that are rare, data-poor, or in changed climates.Read moreRead less
